Fullscreen Mode Linux: Different Behavior Between Menu

Hello everyone,

I have a question about full‑screen mode. I’m using Fedora Silverblue, and when I start the mode via the menu Windows -> Toggle fullscreen mode, I get a different result than when I use the start‑parameter --fullscreen. I’ve attached two screenshots.

     With the --fullscreen parameter, the GNOME panel remains visible. 
     When selecting the option from the menu, the panel is correctly hidden.
     

Am I doing something wrong? The panel should be hidden.

2. Screenshot: --fullscreen https://ibb.co/5XFP9bf4

Additionally, is it possible to start directly in the Jamb View view?

Thanks a lot!
